Rice Is the Primary Nutrient Source for About One-Third of Humanity-Approximately

question 2

Multiple Choice

Rice is the primary nutrient source for about one-third of humanity-approximately 2 billion people worldwide. One major disease of this crop, called rice blight, is caused by a bacterium Xanthomonas oryzae . This disease causes the rice plant to turn yellow and wilt and can affect up to 50 percent of the crop. Wild forms of rice have a natural resistance to the Xanthomonas bacterium, but these wild forms are not usable as crop plants. Scientists have developed a blight-resistant strain, using genetic engineering. Strains of blight-resistant rice have been grown successfully in several countries. What is the first step in the process of transferring the blight-resistant gene from one organism to another?

• A) Identify the gene that you need.
• B) Insert the gene into a plasmid.
• C) Transcribe and translate the gene.
• D) Decode the DNA.
